Heart and Small Intestine, heat syndrome

Lian Qiao is bitter, cold and aromatic, and enters the Heart and Small Intestine meridians. Although it does not enter the Lung meridian, it is still often used in formulas to treat wind-heat syndrome as a chief herb. This is because its aromatic smell can disperse the Qi in the Upper-Jiao and gently release the exterior, and it leaches out heat from the Heart through the Small Intestine. It is especially effective in dispersing and clearing heat in the Heart and relieving restlessness and a warm sensation in the chest.
